Preventative Maintenance Plan

1. Depending on the location of your outdoor project with regard to direct sun exposure, foliage coverage, etc., it may be sufficient to clean/brighten and recoat every two years. 2. If you decide to wait two or more years to perform your next cleaning/brightening, you may want to use a power washer. Be sure that the cleaner/brightener you use contains a mildewcide.

Choosing The Right Stain Or Paint

When determining the right stain and paint for your deck, consider what color will best enhance the wood's finish.

Paint or Stain Tips

If you desire to paint or stain the treated wood project, it is important that the wood be dry enough to accept a coating. The best way to determine if the wood is sufficiently dry to paint or stain is to sprinkle droplets of water onto the wood. If the water droplets are absorbed, the wood is ready to be painted or stained. If the water droplets bead on the surface of the wood, it is too wet. You should wait a few days before attempting to paint and stain the wood.

Pressure-treated timber is treated for protection against termites, fungal decay and rot. With its rustic natural-looking character, this pressure-treated wood is a great choice for a wide variety of outdoor applications, such as play sets, decking, landscaping, walkways and more. For any outdoor projects where lumber will be exposed to the elements, pressure-treated wood is a smart investment. This wood may also be customized with paint or stain to suit your personal preferences.Treated wood is typically still wet when it's delivered to The Home Depot or job site. As it dries, you should expect slight changes in width and length. As lumber dries, it may split, cup and warp. This is more likely to occur to occur in lower-grade boards, where knots and uneven grains are already present. Each piece of lumber is unique and carries physical characteristics that may include the following: knots, warping, shrinkage, swelling and/or splitting.

Answer This Question

A:  Hi Erin, Please consult the warranty that is located in the boxed-off Info & Guides section of the product page. Beyond, that, though, the longevity of wood depends on various factors that include exposure to moisture, sunlight/heat, chemicals, and where it is used (above ground, near-ground, on-ground, or in-ground).

    The treated 6x6’s were used to help control flooding at the rear of my property after snow melt and heavy rains. They worked perfectly to redirect the water away from flooding my yard.
